Dear Lori,
This is in respanse to your second email of December 11, 2015, please see below.
Your Questions
In our interview, you said the following, “Simply said, the protocol that we were using - | do not
believe it is protective of public health and therefore more needs to be done in our testing protocal to
ensure that we're identifying risk. We're addressing lead exposure and we are dealing with the issue
proactively. Flint deserves safe drinking water.”
Are you referring to the method by which the state was testing for lead in the water when you use the
word protocol in this statement?
DEQ Answer:
What was meant by this statement is that the lead and copper rule, as written, was designed to
assess the effectiveness of corrosion control measures utilized by a water supply. It was not
designed to determine individual health exposure risks.
As a result the DEQ has become very proactive in engaging all of our partners to address health
exposure concerns. The testing that is currently being done in the Flint Schools is very rigorous and
goes well beyond any regulatory requirements. We typically take approximately 200-300 samples at
each school in a single sarnpling event. We are evaluating the water mains, the piping throughout the
building as well as the components used such as the salder and fixtures. The good news is that the
testing so far indicates that the issues in the schools are predominantly fixture related and they are
not deep in the plumbing, so the fixes are going to be relatively straight forward.
Once we have completed our evaluation we will use what we have learned to create guidance for all
of the schools in the State of Michigan. In addition we will share our information with the U.S. EPA
and we will partner with them to develop protocols that go beyond corrosion control and focus on
health exposure.
Thank you.
